Upgrading your existing Drupal 7 sites is strongly recommended. There are no new features or non-security-related bug fixes in this release. For more information about the Drupal 7.x release series, consult the Drupal 7.0 release announcement.

Known issues

Due to the nature of the security fix, some sites will require extra testing and care when deploying this release of Drupal core, and several contributed modules require code changes in order to continue working correctly. See the release notes for more information.
